MEF Exporting and Importing abstract types?

Sorted the problem. Silly mistake. The TagManager assembly was not present in the /bin folder and was causing the BaseRmiOperation cstor to crash.

A breakpoint at the start of the cstor was never being called, it always crashed on the line to resolve the OperationFactory. Figured it out by going back to basics and adding functionality one line at a time. Thanks.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
